Hi, I really appreciate your efforts for providing this code snippet,but can you please also send the download link to the complete api?


I am getting Undefined index: uploadType in Google\Service\Resource.php on line 221 exception, when I call the $service->files->insert() method, I have passed all the parameters as shown in the above code.
earlier I was using $service->files->insert($file, array('data' => $data, 'mimeType' => 'image/jpeg'));
changed it to $service->files->insert($file, array('data' => $data, 'mimeType' => 'image/jpeg','uploadType' => 'media'));


@joshiket To solve the warning, you should specify uploadType along with mimeType.
p.s. this piece of code is for V2; please migrate to V3.


can you please update the topic


Hi, I need to setup Google Drive API for one of my project and following the documentation leads me nowhere. The API which I am getting do not have files which are included in the code. Can anyone guide me with the code and API as I am new to APIs.

I need to create a system wherein public users will submit their assignments by uploading Word/PDF files which will be transferred to common Google Drive of teacher and link of each uploaded file will be generated.

Please suggest. Thanks.
